[Boatanchors] News story about risk of high altitude EMP

 Vacuum tube technology is less susceptible to EMP damage. Of course, you have to have backup power for the tube gear if EMP takes the commercial grid down. Ham radio communications probably won't be enough to help much with the widespread problems that would come from a strategic EMP event. (How many of today's hams could put tube stations on the air anyway?) Just about anywhere we could call to for help, that's not too far away to quickly send help, would also be in need of help.

 
Nice to see that NORAD is returning to a defensible location. Their reason for previously moving out was questionable.

Hello Rob,

Where did you do your electronics studies? In journalism
school?

I think you have confused the mains power transmission and
distribution 
grids with the control grids in vacuum tubes.

Try going
here

https://www.google.com/search?q=the+threat+to+melt+the+electric+grid&ie=utf-8&oe=utf-8

and
clicking on the link to the top story in the Wall Street Journal.

It's about
the risk of high altitude EMP.

I mention it here because it seems to me that
vacuum tube gear may be
more immune to the damage of EMP than modern radio
gear.
